However, the EU is moving to regulate this material, highlighting the need for a new type of laminated steel sheet. As basic requirements, the new sheet should have properties equal or superior to those of the conventional lacquered sheets (formability, adhesion, corrosion resistance, release property) without using endocrine disrupters, and should be applicable with existing equipment. ]]> 2016-11-23 13:53:00 UTC https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139588171 anashahirah39 https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139613839 Materials or resin coating which protect the inside of the can from acids in food which would otherwise attack the metal causing it to corrode or damage.]]> 2016-11-23 15:44:52 UTC https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139613839 anashahirah39 https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139617919 1) Dip applied lacquers

Smaller rectangles of steel are then cut and curled into a cylinder and the edges welded together. The bottom end is then seamed on and the empty can is sent to the canner to be filled, sealed and cooked.]]> 2016-11-23 16:44:34 UTC https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139625002 anashahirah39 https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139625715 2) 2 pieces of cans
The two-piece can is a packaging container with the bottom end and the body shaped from one sheet of metal by deep drawing, with a second end seamed to the can to close it and form a complete package for sale. As the whole can is composed of two pieces, it is known as the two-piece can.

2) Enhance product value Outer Lacquering guards.
3) The printed surface Inner Lacquering protects contents Printed. 
4) Lacquered cans enhance the inherent values of tinplate packaging – protection from harmful UV rays and bacteria, retention of original aroma, flavour and colour. 
5) Robust packaging ensures easy storage, stacking and long shelf-life. ]]> 2016-11-23 17:05:05 UTC https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139628731 anashahirah39 https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139749412 2016-11-24 12:16:28 UTC https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139749412 anashahirah39 https://padlet.com/anashahirah39/snh87w6t5uk0/wish/139752060 Lacquer can damage and results in underfilm corrosion,
1) Excessive extrusion marks
~Deep torn marks cut through the lacquer film when enamelling and printing pressure is applied.
2) Cross Scoring
:Little 'sore sports' of broken metal are formed which act as nuclei of corrosion on unlacquered metal and give weak areas of unsupported film in the case of lacquered containars.
3)Knurl Marks
:It is caused by the use of steel knurled points or printing fingers, which grip the container internally in the nozzle or container neck, leaving deep cuts or torn metal.
